The operation check takes out each card from the dispenser, and writes the sample data onto it.
The check then loads and reads it, and checks whether the read data matches the sample data.
Then, the check ejects the card. When you draw out the card at this time, the entire process of the
check is completed. The functionality test uses 1 card from the dispenser.
Select "CLEANING" and press the TEST Button.
If the CARD R/W is not initialized, it will be initialized rst. :INITIALIZE is displayed.
The following message appears to show that the R/W is ready for insertion of the cleaning card:
-- PLEASE INSERT CLEANING CARD --
Insert the cleaning card into the R/W.
On the screen, the status display is replaced with "CLEAN", and cleaning begins.
Once cleaning ends after a lapse of a certain time, the R/W automatically ejects the card.
The status display changes from "CLEAN" to "READY."
NO ERROR is displayed on the screen.

If execution of the operation check results in display of NG, check the error condition. If you can
take action against the error, execute the operation check again after you take the proper action.
If you cannot take action against the error, repeat the check several times. If the result of the
check is still NG, clean the R/W.
If the subsequent execution of the operation check still results in NG, the R/W may be faulty.
If an error occurs, it is cleared by executing the INITIALIZE command.
Note that, when an error has occurred, the R/W only accepts this command (except EXIT).
Cleaning refers to the optional cleaning of the heads on the CARD R/W.
Refer to section <7-2> Head Cleaning for details on the use of the cleaning card.
